Question:
Class 3 Error Report no. 2005-08 states that the temperature is evaluated "elsewhere within the element". Does this mean that the temperature is still being evaluated at the centroid, at a different integration point, or what?
Answer:
The error only affects the coefficient of thermal expansion (CTE), the instantaneous coefficient of thermal expansion.
PLANE42 has 4 integration points. The CTE using the correct temperature at point 1 is called C1, point 2 is C2, etc. Also the CTE using the correct temperature for the element centroid, is CC.
In Release 9.0, the CTE using the temperature computed at point 1 is called A1, point 2 is A2, etc.
Thus, the erroneous usages may be summarized:
A1 = CC
A2 = C1
A3 = C2
A4 = C3
In other words, it's one step behind.
Desired, of course, is;
A1 = C1
A2 = C2
A3 = C3
A4 = C4
which is what is in version 10.0.
